Solution
The correct option is D Natural rubber Nylon and cellulose both have intermolecular hydrogen bonding. Polyvinyl chloride has dipole-dipole interaction.
However, natural rubber is an elastomer. The irregular geometry of the molecules involves weak Van der Waals force of attraction. Hence, the correct option is D
